I am shortly going to be moving to Portugal as a NHR. I am a UK Citizen and already have Portuguese residency. I do NOT yet have a Portuguese driving license. I will be coming to Portugal to get the apartment ready and I want to drive in Portugal for less than 3 Months. Car hire is really expensive. As I said I have a UK driving license. If I were to buy a car to use just for the 3 months and then sell it. What do I do about tax and insurance on the car? All advice welcome
